Do you have any experiance welding? Because the welds are going to need to be done very well for something like this to hold up.

Great point...yes I have some experience welding. Mainly in stick welding, which I've heard is far more difficult than wire feed welding. I plan on building a couple for my mowers and testing them out before I try to sell one for someone else.

I am not planning on mass producing dethatchers in an effort to put jrco out of business...it's more of a side project/hobby during the winter.

I learned to weld in high school shop on a stick welder first, I picked that up really quick. Then we had to learn on a wire welder, I had a very hard time with one of those. Now I have two wire welders and use them alot. A buddy of mine has a stick welder like I learned to weld on at his shop, I cant't weld for crap with a stick welder anymore. I wan't to get a tig welder now so I can learn to weld stainless and aluminum.
